FIG.

  As in FIG. 3A, in FIG. 7A, the handle 10 is rotated, and the height of the folding unit 7 is adjusted while looking at the scales on the left and right measuring tapes 18a. Is shown, and the tatami mat T is placed on the table 2 with the tatami mat facing downward. The folding position of the tatami surface should be preliminarily easy to bend by applying steam, and folds should be attached. The handle 10 and the measure tape 18a are not shown. Further, since the folding unit 7 also has only a mechanism for moving the folding plate 9 back and forth, the frame and the like are not particularly shown.

  In the present embodiment, the frame portion provided with the cylinder 6 shown in FIG. Although not specifically illustrated, a configuration in which the frame portion provided with the cylinder 6 is moved up and down using several cylinders and a guide shaft for lifting and the like can be adopted as a specific structure. A positioning plate 29 is also provided on the moving frame member. This positioning plate 29 is also widened in the width direction like the tatami floor end presser 5, and is constituted by a single plate-like body. Further, as in FIG. 1, the frame portion may be fixed and only the positioning plate 29 may be moved up and down by the cylinder.

  As shown in FIG. 7B, the positioning plate 29 is lowered together with the frame member so that the positioning plate 29 contacts the tatami surface. The force with which the positioning plate 29 abuts the tatami surface does not require a strong pressure. It may be lifted when the operator tries to lift the positioning plate 29 by hand to lift it. Then, with the tip of the positioning plate 29 in contact with the tatami surface, the tatami T is positioned so that the upper surface of the tatami T closely follows the positioning plate 29, and the position of the tatami surface to be folded is confirmed. If the position of the tatami T and the position of the tatami surface to be bent are good, an operation switch or a foot switch (not shown) is turned on.

  When the switch is turned on, the tatami presser 3 and the tatami floor end presser 5 are lowered by the operation of the cylinder 4 and the cylinder 6, respectively, and the tatami T and the end of the tatami T are fixed. (See Fig. 7 (c))

At this time, the tatami table pressed by the positioning plate 29 is bent along the tip of the positioning plate 29 that is in contact with the tatami surface, so that the linearity can be bent. Further, since the swivel bending member 8 bends the tatami surface by swiveling, it can be folded without causing strong friction on the surface of the tatami surface, so that the tatami surface can be folded without being damaged. The turning angle of the turning bending member 8 is about 70 degrees to about 90 degrees by providing a sensor in the cylinder 27 and controlling the air flow in the cylinder to stop when it reaches the sensor position. Fold the tatami mat so that it can be folded. Control may be made so that the bent state is maintained for a predetermined time by a timer or the like.

  When the folding surface is attached to the tatami surface, the tatami floor end presser 5 is raised, and the positioning plate 29 is raised by raising the entire frame portion. As shown in FIG. The adhesive is applied to the entire side surface of the tatami T with a tool. When the application is completed, an operation switch or a foot switch (not shown) is turned on to drive the cylinder 6 and fix the end of the tatami T on the table 2 with the tatami floor end presser 5 as shown in FIG. As shown in FIG. 8 (a), the cylinder 27 is operated to turn the swivel bending member 8, and the swivel bending member 8 presses and adheres the tatami surface to the side surface of the tatami T. Also in this case, since the turning and folding member 8 bends the tatami surface by turning, it can be folded without causing strong friction on the surface of the tatami surface, so that the tatami surface can be folded without being damaged. Further, the tatami surface is bent along the cutting angle on the side surface of the tatami T. However, if the tatami mat is a thin tatami mat, the corner may be crushed depending on the pressure that bends the corner of the tatami T. As shown in FIG. 5a may be provided over the width direction of the tatami floor end presser 5 so that the side surface of the tatami T is not crushed.

By this signal, the tatami floor end presser 5 is raised as shown in FIG. 8 (e), and the tatami presser 3 is raised to complete one side of the tatami surface folding work. The above process is repeated for the other side to complete the folding of the tatami mat T. The embodiment described above that a tape or the like may be appropriately attached to the boundary between the tatami surface fixed to the back surface of the tatami T and the tatami mat may be used as a process for improving the finished product. It is the same.

  Next, the operation of the embodiment using the above mechanism will be described with reference to FIG. In FIG. 1 to FIG. 5, the same members will be described using the same reference numerals, but in order to disclose the operation of the main parts, the detailed structure is not shown in FIG.

  In FIG. 9A, in the case of a thick tatami mat, it is not necessary to adjust the height of the folding unit 7 by rotating the handle 10, and therefore the illustration of the folding unit is also omitted. FIG. 9A shows a state where the tatami mat T is placed on the table 2 with the tatami mat facing downward. The folding position of the tatami surface should be preliminarily easy to bend by applying steam, and folds should be attached.

  The frame part provided with the cylinder 6 is provided as a unit so as to be movable up and down, as in FIGS. As shown in FIG. 9B, the positioning plate 29 is lowered together with the frame member so that the positioning plate 29 contacts the tatami surface. The force with which the positioning plate 29 abuts the tatami surface does not require a strong pressure. It may be lifted when the operator tries to lift the positioning plate 29 by hand to lift it. Then, with the tip of the positioning plate 29 in contact with the tatami surface, the tatami T is positioned so that the upper surface of the tatami T closely follows the positioning plate 29, and the position of the tatami surface to be folded is confirmed. If the position of the tatami T and the position of the tatami surface to be bent are good, an operation switch or a foot switch (not shown) is turned on.

  When the switch is turned on, the tatami presser 3 and the tatami floor end presser 5 are lowered by the operation of the cylinder 4 and the cylinder 6, respectively, and the tatami T and the end of the tatami T are fixed. (See Fig. 9 (c))

  When the fixing of the tatami T and the end thereof is completed, as described with reference to FIG. 6, the cylinder 27 is operated to return the rod 27a, and the rack 26 is moved to the right in FIG. 21 is turned, and the tatami table pressed by the positioning plate 29 is bent by the turning bending member 8 as shown in FIG. At this time, the tatami table pressed by the positioning plate 29 is bent along the tip of the positioning plate 29 that is in contact with the tatami surface, so that the linearity can be bent. Further, since the swivel bending member 8 bends the tatami surface by swiveling, it can be folded without causing strong friction on the surface of the tatami surface, so that the tatami surface can be folded without being damaged. The turning angle of the turning bending member 8 is about 70 degrees to about 90 degrees by providing a sensor in the cylinder 27 and controlling the air flow in the cylinder to stop when it reaches the sensor position. Fold the tatami mat so that it can be folded. Control may be made so that the bent state is maintained for a predetermined time by a timer or the like.

  When the folding surface is attached to the tatami surface, the tatami floor end presser 5 is raised and the entire frame portion is raised to raise the positioning plate 29. As shown in FIG. The adhesive is applied to the entire side surface of the tatami T with a tool. When the application is completed, an operation switch or a foot switch (not shown) is turned on, the cylinder 6 is driven, and the end of the tatami T is fixed on the table 2 with the tatami floor end presser 5 as shown in FIG. As shown in FIG. 9 (g), the cylinder 27 is actuated to turn the swivel bending member 8, and the swivel bending member 8 presses the tatami surface against the side surface of the tatami T to be bonded. Also in this case, since the turning and folding member 8 bends the tatami surface by turning, it can be folded without causing strong friction on the surface of the tatami surface, so that the tatami surface can be folded without being damaged. Further, the tatami surface is bent along the cutting angle on the side surface of the tatami T. However, if the tatami mat is a thin tatami mat, the corner may be crushed depending on the pressure that bends the corner of the tatami T. As shown in FIG. 5a may be provided over the width direction of the tatami floor end presser 5 so that the side surface of the tatami T is not crushed. In the case of a thick tatami mat, the tatami mat does not wrap around the back of the tatami T, so that the folding of the tatami mat on the one end side is completed. The other end is also carried out as described above to complete the Tatami T.

  In the above two embodiments, the case of the thin tatami mat and the thick tatami mat has been described. However, when the tatami mat is folded along the side surface of the tatami mat T, the tatami mat is folded while turning, so the tatami mat may be damaged. Thus, a tatami mat folding machine for edgeless tatami mats that can improve the finish of tatami mats can be provided.

In the above description of the embodiment, the tatami surface is described as being configured to adhere to the side surface and the back surface of the tatami T with an adhesive such as hot melt, but may be fixed with a double-sided tape. Also, in the embodiment described with reference to FIGS. 7 to 9, a hole or a slot that can be stapled may be provided in the swivel bending member 8 so as to be stapled. Moreover, you may employ | adopt the positioning board currently disclosed by FIGS. 7-9 to embodiment disclosed by FIGS. 3-5, and it changes into the structure which determines a position with a laser marker in FIGS. It goes without saying.
